Trek Fuel MX 9 XT Juniper: suspension tuned to your riding

The Trek Fuel MX 9 XT Gen 7 stands out with an Alpha NEXT Platinum aluminium frame with adjustable progression, which lets you tailor the curve of the Fox Factory Float X shock to your style. With 150 mm at the rear, a 160 mm Fox 36 and a 12-speed Shimano XT drivetrain, it weighs 16.91 kg in a size M according to Trek. Its Matte Juniper/Blue Sage Splatter colourway combines a matte juniper green with greyish blue-green spots.

Who is it for?

For the mountain biker who likes to refine their settings and adapt the bike to their weight and terrain, or for the heavier rider who wants suspension that does not bottom out. It will also suit those who alternate technical trails and small jumps.

The LVR workshop view

Why an aluminium Fuel MX? The frame is built from Alpha NEXT Platinum, the top tier of Trek's alloys, ahead of Alpha Platinum and Alpha Silver. On the Gen 7 Fuel platform, the aluminium frame kit (4.95 kg in M, measured on the Fuel EX) weighs 1.64 kg more than the carbon kit (3.31 kg): that is the price of toughness and a controlled budget.

	Alpha NEXT Platinum (Fuel 9)	OCLV Mountain (Fuel 9.8 / 9.9)	Alpha Platinum (Slash 8)
Level	Trek's best aluminium	Trek's mountain bike carbon	High-end alloy, one step below NEXT
Designed to	Take knocks at a sensible cost	Save weight, resist impacts	Aluminium enduro frames
Gen 7 Fuel EX frameset (M)	4.95 kg	3.31 kg	not applicable
What it means	Heavier, but unbothered by small knocks	1.64 kg less on the frameset	Previous aluminium generation

Put simply: alloy does not deprive you of any Fuel MX feature, neither the adjustable progression nor the integrated storage.

Adjustable progression lets you firm up or soften the end of the shock's stroke. A light rider on rough trails will choose a more linear curve to use all the travel; a heavier rider or one who jumps a lot will prefer a firmer end stroke.

The rocker link and lower shock mount are interchangeable, which opens up upgrade possibilities. The ABP system, which separates braking from suspension, keeps the rear end active even when braking through chewed-up sections.

Which Fuel should you choose?

Model	Frame	Travel rear / front	Drivetrain	Weight (M)
Fuel EX 9 XT	Alpha NEXT Platinum alloy	145 / 150 mm	Shimano XT 1x12	17.14 kg
Fuel MX 9 XT	Alpha NEXT Platinum alloy	150 / 160 mm	Shimano XT 1x12	16.91 kg
Fuel MX 9 XT Di2	Alpha NEXT Platinum alloy	150 / 160 mm	Shimano XT Di2 1x12	not disclosed
Fuel LX 9 XT	Alpha NEXT Platinum alloy	160 / 170 mm	Shimano XT 1x12	17.79 kg

Our take: the MX 9 XT and MX 9 XT Di2 share frame and suspension; the Di2 stands out with its electronic drivetrain. The Fuel LX 9 XT (17.79 kg) moves to 160/170 mm for enduro.

LVR sizing advice

If you are between two sizes, the smaller favours handling in switchbacks and slow sections, the larger brings stability as speed rises. Dropper post travel follows frame size.

Size	S	M	L	XL
Rider height (cm)	155-165	165-177	177-188	188-195
Inseam (cm)	74-78	79-83	84-89	89-91
Dropper post (mm of travel)	150	170	200	200
